为使交流等离子体显示器(AC PDP)中单纯累积发光模式产生更好的灰度显示效果
提出了一种改进型自适应子场编码驱动方法.该方法在比例较小的子灰度区间
对子区间内灰度级的累积概率密度进行采样处理
将采样灰度值定位在子区间内灰度概率密度值大的灰度级上; 在比例较大的子灰度区间
直接对子区间内灰度级进行采样处理
以避免采样灰度值过于集中造成的较大量化误差
最终能够使由采样灰度值产生的各子场编码权值表达出最丰富的原始图像信息.仿真结果表明
提出的方法除了能够消除AC PDP动态假轮廓现象以外
在灰度级表现力上还优于现有文献中的类似方法
能够更好地再现原始图像信息.
An improved adaptive subfield coding driving method is proposed to obtain better grayscale expression capability when the ‘simple-accumulation'-lighting-mode is applied to alternating current plasma display panels(AC PDPs). The proposed method samples the gray cumulative probability densities in the sub-grayscale interval with small weighted ratio to locate the sampling gray levels where the gray probability densities are larger. The gray levels in the sub-grayscale interval with large weighted ratio are directly sampled so as not to generate larger quantization error caused by the excessive concentration of the sampling gray levels. The subfield vector obtained by the sampling gray levels can express the most grayscale information of the original image. Simulation results show that the proposed method can eliminate the dynamic false contours in AC PDPs
and is superior to existing similar methods in grayscale expression capability
hence the proposed method can reproduce the original image information more faithfully.
